so, i got the whole thing thats been discussed here several times, to
reiterate for the context of this question,

1. create branch B off of branch A
2. at various points, svn merge from A -> B
3. at some other point (after those downstream merges) svn merge
--reintegrate B -> A

now, i understand the need to svn rm B, and recreate it. however, here is
my question..

suppose after the initial reintegration merge from B -> A, there will be *no
more* downstream merges from A -> B. that should avoid the need to recreate
B, right? so then the main thing id like to do is multiple --reintegrate
merges from B -> A, w/o recreating it each time, given that there will be no
more downstream merges from A -> B. is that reasonable, or is there some
danger i should know about?
